Angle Of Nip In Roll Drying Machinery Function Pdf
Roll Crushers
· The nip angle is affected by the distance between the rolls. The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40 ......
